Weatherwise is a magazine published by the American Meteorological Society. One issue gives a rating system used to classify Nor'easter storms that frequently hit New England and can cause much damage near the ocean. A severe storm has an average peak wave height of u = 16.4 feet for waves hitting the shore. Suppose that a Nor'easter is in progress at the severe storm class rating. Peak wave heights are usually measured from land (using binoculars) off fixed cement piers. Suppose that a reading of 34 waves showed an average wave height of x = 16.7 feet. Previous studies of severe storms indicate that o = 3.5 feet. Does this information suggest that the storm is (perhaps temporarily) increasing above the severe rating? Use a = 0.01.

How well does the line describe the data? What is the mileage that you would expect a 4000-pound car to have?

In West Texas, water is extremely important. The following data represent pH levels in ground water for a random sample of 102 West Texas wells. A pH less than 7 is acidic and a pH above 7 is alkaline. Scanning the data, you can see that water in this region tends to be hard (alkaline). Too high a pH means the water is unusable or needs expensive treatment to make it usable.† These data are also available for download at the Companion Sites for this text. For convenience, the data are presented in increasing order.   Make an ogive using five classes. (Graph each point and the closed line segments connecting the points to create your graph.)

According to an exit poll for an election, 55.1% of the sample size of 819 reported voting for a specific candidate. Is this enough evidence to predict who won? Test that the population proportion who voted for this candidate was 0.50 against the alternative that it differed from 0.50. Complete parts a through d below. OD. The parameter is the number of voters that voted for the candidate. Define the notation for the parameter. OA. p= the number of voters that did not vote for the candidate OB. p= the number of voters that voted for the candidate C. p=population proportion of voters that voted for the candidate D. p=sample proportion of votes for the candidate b. State the hypotheses and check the assumptions for a large-sample test. Choose the correct answer below. O A. Ho: p=0.50; H₂: p0.50 The assumptions for a large-sample test are met. c. Report the test statistic and P-value and interpret the latter. (Round to two decimal places as needed.) ... D F (1) More x

A gambler knows that red and black are equally likely to occur on each spin of a roulette wheel. He observes that 5 consecutive reds have occurred and bets heavily on black at the next spin. Asked why, he explains that "black is due.” Explain to the gambler what is wrong with this reasoning. un ¹. O X b. After hearing you explain why red and black are still equally likely after 5 reds on the roulette wheel, the gambler moves to a card game. He is dealt 5 straight red cards from a standard deck with 26 red cards and 26 black cards. He remembers what you said and assumes that the next card dealt in the same hand is equally likely to be red or black. Explain to the gambler what is wrong with this reasoning. b Due for a hit A very…
